Active clinical trials for "Glucose Intolerance"

The purpose of this study is to investigate the effects of Chromium on glucose tolerance and endothelial function in people at risk for type II diabetes.

The primary aim of this study is to evaluate the effect of exenatide on daily glycemic excursions obtained by continuous glucose monitoring system (CGMS). The CGMS summary parameters that we are most interested in include: The percent of glucose values above 140 mg/dl and/or AUC of glucose values above 140 mg/dl AUC of glucose values over 100 mg/dl during three days Maximal meal-related glucose excursions Three-day mean glucose (including low readings - below 100 mg/dl) Secondary Study Endpoints: Secondary endpoints will include: glucose tolerance status as assessed by OGTT Vascular function scores as assessed by PAT, FMD and step test. Biochemical markers of vascular health, including inflammatory markers, markers of oxidative stress and microalbuminuria. Changes in BMI

Randomized, double-blind, crossover-trial, 30 subjects in each groups, either males or females, normal fasting glucose or pre-diabetes, aged > 18 years old to perform oral sucrose tolerance with either one of the 5 study products Sucrose 50 g Sucrose 50 g + D-allulose (psicose) 2.5 g Sucrose 50 g + D-allulose (psicose) 5 g Sucrose 50 g + D-allulose (psicose) 7.5 g Sucrose 50 g + D-allulose (psicose) 10 g Primary endpoints: To investigate the dose-response effects of D- allulose (psicose) with sucrose beverage on glucose tolerance To investigate the dose-response effects of D- allulose (psicose) with sucrose beverage on insulin levels

Cardiovascular disease (CVD) is the leading cause of death in the United States. Short-term increases in blood sugar, or postprandial hyperglycemia (PPH), affect blood vessel function and increase the risk of CVD. Greater intakes of dairy foods have been associated with a lower risk of CVD, but whether these effects occur directly or indirectly by displacing foods in the diet that might increase CVD risk is unclear. Further controversial is the extent to which dietary fat derived from dairy foods regulate the risk of CVD. The health benefits of dairy on CVD risk are at least partly attributed to its ability to limit PPH and resulting PPH-mediated responses leading to vascular dysfunction. This provides rationale to investigate full-fat containing dairy as a dietary strategy to reduce PPH and risk for heart disease. The objective of this project is to define the extent to which full-fat dairy milk compared to non-fat dairy milk protects against PPH-induced vascular dysfunction by reducing oxidative stress responses that limit nitric oxide bioavailability to the vascular endothelium in adults with prediabetes.

Obesity and pre-diabetes threatens the overall health and functional independence of older adults but lifestyle weight management for diabetes prevention, soon to be reimbursed by Medicare, can reduce this burden. The current 24-month study will enroll adults, ages 60 and older, through senior community centers and research registries. The investigators will study how two long term weight loss maintenance programs, both using group telephone sessions to support health behavior change, impact meaningful health outcomes. If successful, this project will provide a sustainable intervention model for healthy aging services that can benefit older adults and society.

Hypothesis Prediabetes patients who have insufficient sleep will have worse glucose tolerance than those with normal sleep duration. Prediabetes patients with short sleep will have a delayed or reduced GLP-1 response to a standardized meal

The study is a 2-arm, multicenter, 1:1 randomized, placebo controlled clinical trial. All subjects will receive close monitoring for development of AGT or T1DM. Subjects will receive Abatacept or placebo and close monitoring for development of AGT or T1DM. To assess the safety, efficacy, and mode of action of Abatacept to prevent AGT and T1DM. The primary objective is to determine whether intervention with Abatacept will prevent or delay the development of AGT in at-risk autoantibody positive non-diabetic relatives of patients with T1DM. Secondary outcomes include: the effect of Abatacept on the incidence of T1DM; analyses of C-peptide and other measures from the OGTT; safety and tolerability; and mechanistic outcomes.

Insulin resistant subjects and type 2 diabetic patients are characterized by a decreased metabolic flexibility: a reduced capability to switch from fat oxidation in the basal state to carbohydrate oxidation in the insulin-stimulated state. This metabolic inflexibility is an early hallmark in the development of diabetes. Recent evidence suggests that a low carnitine availability may limit acetylcarnitine formation, thereby reducing metabolic flexibility. We propose to test the hypothesis that metabolic inflexibility in pre-diabetic subjects and diabetic patients is due to a reduced capacity to form acetylcarnitines.

To examine whether a lifestyle program results in weight loss and thereby delays or prevents progression of pre-diabetes to diabetes, we propose a pilot randomized controlled trial of 6 weeks duration with 30 participants held at Stephanie Tubbs Jones Health Center. Participants are randomized to receive all of the following: nutrition education, exercise instruction, stress management instruction, and culinary education or follow usual care. Outcomes include: blood sugars and cholesterol, weight, waist circumference, blood pressure, diet, physical activity, perceived stress, and class attendance. Analysis is by Intention to treat analysis of variance. Results will be used to help design larger randomized trial in the future.

The investigators plan to test two different strategies for weight loss and diabetes prevention in the Latino community in and around Forsyth County, North Carolina. The study is designed to test the hypothesis that a lifestyle weight-loss program implemented within the Latino community will have a more beneficial and clinically meaningful impact on hemoglobin A1c (HbA1c), insulin metabolism, and markers of the metabolic syndrome when compared to an enhanced usual care condition. This lifestyle intervention will include group-based sessions promoting healthy eating, increased physical activity and weight loss. These sessions will be delivered by lay community members, known as Latino Health Advisors (LHAs). The enhanced usual care group will consist of individual counseling with are registered dietitian and uses existing community resources to assist participants in making healthier lifestyle choices.
